[Discuss-gnuradio] misterious symetrical signal

[nexy_sm]

Hallo people,

During my adventure of designing 433MHz receiver i have recently discovered
misterious simetrical signal which I am not able to explain to myself. I am
using USRP1 with WBX daughter board. While observing complex baseband
signal, I realized that depenting on RF gain I have a signal simmetrical to
the transmitted signal. I have also attached a photo.

Hope that you have some explanation.
